Distribution of contact pressure between the bipolar plate and gas diffusion layer considerably affect the performance of proton exchange membrane fuel cell. In this regard, an adaptive neuro-fuzzy inference system (ANFIS) is developed to predict the contact pressure distribution on the gas diffusion layer due to dimensional errors of the bipolar plate ribs in a proton exchange membrane fuel ce...

Dear Editor-in-Chief, Influenza, commonly known as the flu, is an infectious disease caused by an influenza virus (1). Symptoms can be mild to severe (2). The most common symptoms include: high fever, runny nose, sore throat, muscle pains, headache, coughing, sneezing, and feeling tired (1). Three of the four types of influenza viruses affect people, Type A, Type B, and Type C (3, 4). Type D ha...

background: to correct patient positioning errors (setup errors) during prostate cancer treatment using epid and fiducial gold markers, to improve the accuracy of the dose delivery in these patients. materials and methods: fifteen patients with localized prostate carcinoma after implantation of fiducial gold markers in their prostate gland underwent the five-field imrt planning technique. the p...

Automated writing evaluation (AWE) software is an increasingly popular tool for English second language learners. However, research on the accuracy of such has been both scarce and largely limited in its scope. As such, this article broadens field AWE by using a mixed design to holistically evaluate corrective feedback leading program Grammarly. 1136 Grammarly-identified errors related style, l...

The topic of this thesis is about soft-errors in digital systems. Different aspects of soft-errors have been addressed here, including an accurate simulation model to emulate soft-errors in a gate-level net list, a simulation framework to study the impact of soft-errors in a VHDL design and an efficient architecture to minimize the impact of soft-errors in a DSP processor. The first two chapter...

Background and Aim: Cardiovascular diseases and medication errors are among the leading causes of morbidity and mortality around the world. Electronic prescribing and Medication Administration(ePMA) systems can prevent medication errors to some extent. This study aimed to determine the information requirements of ePMA systems. Materials and Methods: This descriptive study was conducted in Imam...

no unique method has been so far specified for determining the number of neurons in hidden layers of multi-layer perceptron (mlp) neural networks used for prediction. the present research is intended to optimize the number of neurons using two meta-heuristic procedures namely genetic and hill climbing algorithms. the data used in the present research for prediction are consumption data of water...

Simultaneously pressing two keys on a keyboard (Zero Time keystrokes) is a unique typing occurrence. To understand the cause of Zero Time keystrokes, typing data were collected from young children and undergraduate computing students. The results show that, in both students and children, the most frequent cause of Zero Time keystrokes were errors in aiming for the intended key, resulting in the...
